applicati@ med september My invention relates to concrete molding and more particularly it relates to an improved tool for removing the spacer elements for the side -walls of concrete molding forms. l

, An object o f my invention is to provide a tool of length and weight sufficient to enable an operator to knock the-spacer elements from a position between the side walls of the concrete form after the concrete hasbeen poured and set for a short lperiod of time, and in which provision is made to-facilitate ready withdrawal of the spacer elements from the form after they have been dislodged from engagement with the mold form side walls.

Another object of my invention resides in the provision of a tool of the class referred to .which is durable, economical to produce and which may be readily handled efficiently.

rFliese and other objects of my invention and the invention itself will become apparent from reference to the following description of an embodiment thereof and in which description reference will be had to the accompanying drawings forming a part l of this specification.

Referring to the drawings: Fig. 1 is a perspective View of a section of a concrete molding form illustratingan embodiment of my invention in perspective and depicting one mode of operation of the same; Fig. 2 is a View partly in sectionand partly -v in elevation of an embodiment of my invention; and l Fig. 3 is an elevational view ofthe above embodiment. v

Referring to all the figures of the drawings in all of which like parts are designated by like reference characters, at 10, I show an elongated impact head preferably formed of solid metallic material, such as steel and havinga serrated impact striking surface 11 and a serrated sidewall 12. A slot 13 is formed in the head intermediatethe ends thereof, and the upper portion of the head is formed in cylindrical shaped portionv at 14, which portion is provided with a longitudinally extending threaded bore 15.

At 16. I show preferably an elongated wooden handle for the tool, having an intermediate gripping'portion and an enlarged end portion 17 to prevent the hands of the operator from slipping off the end of the same in use. The opposite end of the handle is threaded at 18, which is adapted to be screwthreaded into the threaded bore 15'of the head to provide an adjustable connection'between v1o, 1927. serial No. 218,844.

lengthening or shortening the tool as'desired.

I preferably employ substantially J- shaped grapple j aw element 20, having a relatiyely long hook shaped portion 21 provided with a toothedgripping end (22, and a relatively short arni 23, disposed in the slot 13 ofi the head, with the arm 21 thereof projecting.

to one side of the head with its end 22 disposed adjacent the serrated portion l2 of the head, and with the other arm portion 23 projecting laterally of the opposite side of the head. lA transverseV bolt 25 extends acrossl the slot onto which' is pivoted the grapple jaw element 20, the bolt being secured on the head spanning 4the slot, by virtueof a nut 26. The outermost end of the relative-ly short arm 23 1s provided 4with an eyelet 30 into whlch one end 31` of a long wire rod 32 is inserted and secured therein against accidental disengagement by twisting the same. This wire rod extends upwardly substantially parallel with the head and handle and is secured to the handle adjacent the upper end thereof.

A.A manually operable handle lever comprlsinga hand'gr1pportion 36, a laterally extending portlon 37 pivoted at 38 to the handle adjacent the upper end thereof, and

also being provided with an arm 39 having an eyelet 40 adjacent the V'endther'eof into which is projected and secured by twisting it atv 41 the upper end of the wire rod 32. .A retractile coil spring 42 is provided for holding theV handle lever in the position shown in full lines in the drawings andhavingone end thereof secured in an eyelet 43, in the arm 39 adjacent the eyelet 40, andv the vopposite end ,thereof being fastened in an eye-bolt 44 secured to the handle 16 below the bolt v38. The operating handle 35 is preferably formed of sheet metal and-'the handle portion 36' thereof, preferably rounded in'its crosssectional dimensions to enable the same to assume theposition indicated in dotted lines at 50, when it 1s swung on its pivot at which position a U-shaped sheet metal latch 51,`

pivoted at 52 adjacent the upper end o-f the handle 16, may be swung into the position illustrated in dotted lines at 53, to retain the handle portion 36 lof the operatinglever in substantial contiguous parallel relation with the handle 16. When so positioned the arm 39,

spring 42', rod 32 and J-shapedgrapple jaw lever 20 assume the respective positions indicated in'dotted lines in Fig. 2 of the drawings.

The rod ,32 may be provided with a turn buckle 60 to facilitate adjustment thereof commensurate with the relative adjustment of the head 1() and handle 16. However, the rod may be made of Wire material, which will enable it to belengthened by straightening the twisted ends 31 and 41 thereof.'

' The use of the afore described tool, as best shown in Fig. l, maybe as follows:

Two by four uprights, such as 68 and 69 are commonly employed to brace side wall planks 7() and 71 of the usual concrete molding form, now in common use, these planksl being secured together by virtue of a plural'- ity of wires 73 twisted about each other and projected through apertures in the planks and being looped at 74 about these uprights.

Short wooden horizontally disposed spacer elements 7 5 are generally employed to hold l the side walls apart by being jammed or wedged between the side planks 70 and 71 of the form. It hasheretofore been the prac.

tice to remove these spacer elements from the form after the concrete has been poured and partly settled, as shown at 80 inthe drawings, the concrete mass 81 having sufficiently hardened to permit removal 4of the side planks of the form.

Great difiiculty has heretofore been encountered in withdrawing these spacer elements after the'concrete has been poured to a depth wherein the spacer element 82 is partially imbedded therein. An operator desirin to withdraw; spacer elements so im-I bedded after the concrete has settled suficiently to render it partially self sustaining in form together with the side wall planks of the mold, may strike an end of thevspacer element 82 with suficient force to dislodge it from a horizontal position wherein its ends are wedged between the side wall planks of the form and when so dislodged, he may then grip the dislodged spacer element with the jaws 22 and 12 of the grap le by a pull on v an impact striking surfaceadapted for striking the spacer elements to discngage it with the side walls of the form, a long handle for the head secured thereto at its non-striking vend and extendlng in substantial alignment therefrom, a substantially J-shaped grapple jaw element pivoted to the head at an intermediate portion of its longer arm and'having the end of its shorter arm comprising a movable jaw projected to one si-de of the head,

1 and the endlof its longer arm projected to the opposite side thereof, a jaw actuating spring retractinglever pivoted to the end of the *A handle remote from the head, `said head presenting a roughened jaw surface on its head towards the pivotal jaw', and a rod disposed L 'aIQngthe side of the head adapted to communicate movement of the lever to the end of the grapple jaw element,
